Camera Zoom ring bent and now says turn off and on again over and ove?

I presume the zoom ring is stuck partially or fully extended and is visibly out of alignment. The way that these zoom lenses work is that the barrel that moves in and out has several pegs which slide in helical grooves in the inside of a slightly larger barrel. One of these pegs has probably slipped out of its groove but hopefully not broken. If you grip the zoom barrel firmly in one hand and the camera body in the other you may be able to force it back. Good luck!
